This patch adds sysupgrade, uboot-env and networking support
for Methode uDPU device.
Device features 4 partitions:
-----------------------------------------
| boot | recovery | rootfs | misc |
| (ext4) | (ext4) | (fsf2) | (f2fs) |
_________________________________________
Idea was to use f2fs only but the u-boot currently lacks support
so first 2 partition are ext4 to be u-boot readable, and this was
a reason why custom build and sysupgrade sections were required.
On the sysupgrade, boot and rootfs partitions are updated, firmare
image and user configuration is saved on the misc partition and if
the upgrade was successfull, recovery partition will be updated on
after the reboot from preinit script. If the sysupgrade fails for any
reason, device will fallback to recovery initramfs image.

Consistently handle boot-count reset and upgrade across
ipq40xx, ipq806x, kirkwood, mvebu
Dual-firmware devices often utilize a specific MTD partition
to record the number of times the boot loader has initiated boot.
Most of these devices are NAND, typically with a 2k erase size.
When this code was ported to the ipq40xx platform, the device in hand
used NOR for this partition, with a 16-byte "record" size. As the
implementation of `mtd resetbc` is by-platform, the hard-coded nature
of this change prevented proper operation of a NAND-based device.
* Unified the "NOR" variant with the rest of the Linksys variants
* Added logging to indicate success and failure
* Provided a meaningful return value for scripting
* "Protected" the use of `mtd resetbc` in start-up scripts so that
failure does not end the boot sequence
* Moved Linksys-specific actions into common `/etc/init.d/bootcount`
For upgrade, these devices need to determine which partition to flash,
as well as set certain U-Boot envirnment variables to change the next
boot to the newly flashed version.
* Moved upgrade-related environment changes out of bootcount
* Combined multiple flashes of environment into single one
* Current-partition detection now handles absence of `boot_part`
